For The First Time Ever, Astronomers Detect Light From a Black Hole Collision

For the first time, astronomers have seen a flash of light from the collision of two black holes.

The objects met and merged 7.5 billion light-years away, within a vortex of hot, swirling matter circling a larger, supermassive black hole.

That seems perfectly reasonable.Light seen in what telescope? At what wavelength? Found it. “Palomar Observatory … Zwicky Transient Facility”.

Technical article at https://journals.aps.org/prl/abstract/10.1103/PhysRevLett.124.251102

Observed in red an green colour bands. The flash of light started 20 days after the gravitational waves and peaked 50 days after the gravitational waves. A bit slow, perhaps? Or perhaps gravity travels at a speed that is a whisker faster than the speed of light.
